Weather in June
Temperature
The start of June brings a shift in the average high-temperature, increasing from May's agreeable 72°F (22.2°C) to a warm 81.7°F (27.6°C). During June, the nighttime temperature averages of 64.8°F (18.2°C).Heat index
For June, the heat index is appraised at a hot 87.8°F (31°C). Prolonged activity during exposure might result in a state of fatigue and cause heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
